DENVER -- Investigators believe Joshua Cummings, 37, targeted RTD security officer Scott Von Lanken in what's being described as an execution-style killing. Sources said Cummings describes himself as a radical Muslim.

Law enforcement sources also said Cummings was arrested with jihadist materials inside a backpack. Cummings, who is from Texas, was arrested in Austin, Texas, in 2010 for assault.

Late Wednesday, police officers were outside the Holiday Motel at 4475 S. Broadway in Englewood. The manager said Cummings lived in a room with his wife and baby over the past few weeks.

The manager also said FBI agents and police officers were at the motel, investigating Cummings weeks ago.

A neighboring business owner backed up that story, saying a police officer told him Cummings was being investigated for unusual Facebook posts.

FBI agents refused to comment on Wednesday. Cummings’ father had no comment.
